Per- and polyfluoroalkyl substances ( PFAS [1] or PFASs [2]) are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain; there are 7 million such chemicals according to PubChem. [3] PFAS came into use after the invention of Teflon in 1938 to make fluoropolymer coatings and products ...
PFAS then accumulates the biomass in fish, wildlife, ecosystems and humans. Two of the primary compounds of concern, PFOA and PFOS, pose a host of potential risks, particularly to children and ...
Here's how Rockford area water systems are preparing for new stringent EPA standards for PFAS "forever chemicals." ... Construction of the new plant is expected to begin in 2025 and be done in 2026.
Firefighters in Connecticut are seeking millions from 3M, DuPont and other companies for being exposed to toxic levels of "forever chemicals" in firefighting gear. The firefighters say they have ...
PFAs. Per- and Polyfluoroalkyl Substances – also known as PFAs – are widely used, long lasting chemicals found in many consumer, commercial, and industrial products. Breaking down very slowly in the environment, PFAs have been found in water, air, fish, soil, the blood of humans and animals, and food products around the world.
This timeline of events related to per- and polyfluoroalkyl substances (PFASs) includes events related to the discovery, development, manufacture, marketing, uses, concerns, litigation, regulation, and legislation, involving the human-made PFASs. The timeline focuses on some perfluorinated compounds, particularly perfluorooctanoic acid (PFOA ...
In short, the rule sets limits on several common types of PFAS. The EPA says there is enough evidence to limit PFOA and PFOS at the lowest level they can be reliably detected. For some other types ...
The International Living Future Institute (ILFI) has developed the following red list of chemicals that may not be included in materials used in construction that seeks to meet the criteria of the Living Building Challenge (LBC). According to ILFI, the list is composed of materials that should be phased out of production due to health concerns.
